Unabyss
Unabyss
Self-updating universal context layer that provides segmented, persistent context to agents and LLMs via the MCP connector protocol.
Key features
- Self-Updating Context Layer: Continuously ingests and refreshes relevant documents, events, and interaction history so connected agents always receive current context without manual updates.
- MCP-Native Connector: Exposes context through the MCP connector protocol, enabling any MCP-capable agent or LLM to request and consume the same shared context surface.
- Segmented Access Controls: Context is segmented by default to enforce boundaries between projects, users, or data classes, reducing accidental exposure of private information.
- Persistent Cross-Session Memory: Stores and surfaces long-lived context across sessions, addressing short-lived model memory and improving multi-step task continuity.
- Automatic Context Prioritization: Selects and supplies the most relevant context for a given prompt or agent task, reducing prompt size and minimizing irrelevant data sent to models.
- Agent-Agnostic Integration: Works with multiple agents and LLM backends (via MCP), allowing teams to centralize context management without coupling to a single model provider.
- Persistent, session-spanning context storage to address short-term memory limits
- Self-updating context that automatically evolves without manual prompt engineering
